The Spirit Tower has its guardian, but unless it understands who its guardian is, it cannot be guarded. - Zhuangzi

昔者庄周梦为蝴蝶，栩栩然蝴蝶也，自喻适志与，不知周也。俄然觉，则戚戚然周也。不知周之梦为蝴蝶与，蝴蝶之梦为周与？周与蝴蝶则必有分矣。此之谓物化。

Chuang Tzu's wife died and Hui Tzu came to console him, but Chuang Tzu was sitting, legs akimbo, bashing a battered tub and singing. Hui Tzu said, 'You lived as man and wife, she reared your children. At her death surely the least you should be doing is to be on the verge of weeping, rather than banging the tub and singing: this is not right!' Chuang Tzu said, 'Certainly not. When she first died, I certainly mourned just like everyone else! However, I then thought back to her birth and to the very roots of her being, before she was born. Indeed, not just before she was born but before the time when her body was created. Not just before her body was created but before the origin of life's breath. Her life's breath wrought a transformation and she had a body. Her body wrought a transformation and she was born. Now there is yet another transformation and she is dead. She is like the four seasons in the way that spring, summer, autumn and winter follow each other. She is now at peace, lying in her chamber, but if I were to sob and cry it would certainly appear that I could not comprehend the ways of destiny. This is why I stopped.<nowiki/>'

Once upon a time, I, Chuang Tzu, dreamt that i was a butterfly. flitting around and enjoying myself. I had no idea I was Chuang Tzu. Then suddenly I woke up and was Chuang Tzu again. But I could not tell, had I been Chuang Tzu dreaming I was a butterfly, or a butterfly dreaming I was now Chuang Tzu? However, there must be some sort of difference between Chuang Tzu and a butterfly! We call this the transformation of things.
